WINDOW CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 769,803, dated September 13, 1904.

Application iled January 26, 1904. Serial No. 190,730. (No model.)

To all whom it may concern:

Be it known that I, EDWUND H. LUNKEN, a citizen of the United States, residing at Oincinnati, Ohio, have invented certain new and useful Improvements in Window Constructions, of which the following is a specification.

My invention relates to window constructions, and I have shown it embodied in the general style of window disclosed in applications for Letters Patent of the United States, filed by Bernard J. Hausfeld and myself as joint inventors, September 14, 1903, Serial No. 173,118, and January 9, 1904, Serial No. 188,199.

In the window constructions referred to a metallic main frame is arranged in the window-opening and carries pivotally a secondary frame arranged to swing into diiferent positions. My present invention concerns more particularly a blind or shutter arrangement in connection with the window whereby the entrance of the light-rays may be regulated and different lighting effects secured and whereby also when the secondary frame is swung on its pivots into an inclined position the blinds or shutters may serve as an awning and one that is capable of adjustment as desired.

The invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a central vertical sectional view of a window construction with my invention combined therewith. Fig. 2 is a perspective View in detail, partly in section. Fig. 3 is a sectional plan view through one of the shutter-carriers with one of the blinds or shutters removed. Fig. 4 is a view of a detail.

In the drawings, 1 is the main frame, and 2 the secondary frame, pivoted to the main frame at 3, so that it may be swung in a vertical plane into diierent inclined positions.

My blind or shutter arrangement comprises two carriers 4 and 5, adapted to run in guideways 6 7, extending vertically of the secondary frame directly adjacent each other and parallel. The carriers are connected with each other by a cord 8 or other flexible medium extending over a guide-pulley 9 and having its ends connected to the carriers, so that they may be moved in unison. Each carrier has a plurality of shutters or sun-blinds thereon, and I have shown three of these. The one marked 10 is fixed to the carrier at a point about midway of its height, while the other two are movable in guide-grooves 11, extending vertically near opposite edges of the carrier and parallel with each other. The movable blinds or shutters of each carrier are connected by a cord 12, passing over a pulley 13 at or near the top of the carrier, so that they will move in unison, and when one is raised the other will fall. In addition to these blinds or shutters I also employ a sun-shade or blind 14, connected with a spring-roller 15 journaled in bearings on the upper carrier, said sun-shade depending from the upper carrier and being capable of being drawn down to the point desired like an extensible curtain.

As shown in Fig. 1, when the shutter-carrier 4 is all the way down the other carrier, with its shutters or blinds, is all the wayfup; but by raising the lower carrier the upper carrier will be allowed to descend, and thus the shutters may be adjusted to various positions vertically to secure different shading effects. Further than this each set of shutters-z'. e., those supported on each carrieris capable of adjustment to afford different Ventilating or shading effects. For instance, the set of shutters on the upper carrier are shown as spread out in relation to each other to obstruct the opening at the top of the window, while the set of shutters or blinds on the lower carrier are assembled in relation to each other, the two movable members being arranged at the sides of the lixed member, thus presenting a minimum obstruction to the opening at this point. The two sets of shutters may be brought to a central position side by side, and each set may in itself be assembled so that the obstructions at the center of the window-opening will then be equal only to the height of a single shutter section or member, or either or both sets may be spread to a greater or less degree, and the carriers themselves may be separated vertically to any desired extent. In this way va- IOO rious degrees and` conditions of ventilation may be secured, and the same is true of the shading effects.

I prefer to form the adjustable shutter-sectioris/ofiiietal and in the forni of plates having their side edges running in the grooves of the carrier in the case of the movable shutters, and in case of the fixed shutters the side edges are simply embedded in the carriers. These plates are provided with inclined slats of substantially ordinary form.

Leaf-springs 16 are secured to one edge of the bottom shutter in each carrier, and spring 17 is likewise secured to one edge of the bottom carrier. The frictional restraint afforded by these springs prevents the shutters from jarring open and also in case of a slight overweight will hold the shutters in position. Also when it is desiredto wash the windows on their exterior side the frame is swung vertically when horizontally pivoted, and unless some provision was made to hold the bottom shutters and lower carrier in place they would by gravity fall to the bottom. I also provide a stop 19 on each carrier at the top of the grooves for each movable shutter, so as to prevent their falling out when the secondary frame is reversed. To insure the bottom carrier from falling when the window is swung, I provide a lock 18 on the carrier.

It will be seen that with my invention when the secondary frame is in closed position ventilation may be had at the top of the window without causing the draft to affect the flexible curtain to any annoying extent by sim- 'ply lowering the upper sash, say, to the plane of the lower end of the Lipper carrier. The air-current will now pass entirely above the curtain through lthe slatted shutters or more freely through the spaces, which may be provided at will by adjusting the said shutters to their middle position. Further, the iexible curtain follows the adjustment of the upper member of the blind or awning, being attached to the carrier thereof, and it will be further noticed that the flexible curtain is used to shield the space between the upper and lower main members of the blind, and thus the whole window may be controlled as ,to the passage of the light. When it is desired to wash the inside of window, both carriers canl culation of air is obtained, and the sun is entirely excluded when the curtain 14 is lowveaso's ered. As the sash at all times shield the curtain from the direct current of air, the annoyance of a swinging curtain is overcome.

With my improved arrangement of shades quite a number of combinations of shade effect can be obtained, and it can be applied to great advantage to the present form of wooden windows operated by weights. other words, I do not limit myself to any particular style of window with which my invention is associated.

Instead of a plurality of shutters, as heretofore described, it is evident that the carriers 4 and 5 need have but one shutter attached thereto for a more simple forni of blind when desired, this being considered parture from my invention.

Itis evident that the lower blind can be dispensed with and the upper blind remain at the top of the window in which a plurality of shutters can be arranged and operatedby a cord. The curtain then would have to be longer, so as to cover the opening between the shutter and sill.

I do not wish to limit myself to the arrangement in which the balanced shutters move on opposite sides of the stationary-member, as a different arrangement may be employed.

It will be understood that the light-shade or blind described above also answers the purpose of an awning when the swinging Vframe is adjusted to inclined position,l and the terms light-shade and blind are meant to cover such use of these parts.
